There are 561 7th and 8th graders at Lafayette Middle School. There are 42 fewer than seventh graders than twice the number of 8 graders. How many seventh graders are there?

If there are x 8th-graders, then there are 2x-8 7th-graders. So,
2x-8 + x = 561
Now finish it off
I suspect a typo, especially since
"There are 42 fewer than seventh graders than twice the number of 8 graders." makes no sense.
